Shuttle vectors for the introduction of DNA into mycobacteria and utilization of such bacteria as vaccines

摘要

Shuttle vectors for inserting DNA in mycobacteria including at least one origin of functional replication in said mycobacteria, another origin of functional replication in other bacteria, an enzyme cutting site allowing the insertion of DNA coding for a protein capable of being expressed in the mycobacteria, wherein the shuttle vectors also carry a gene providing on said mycobacteria resistance to a compound containing a heavy metal.
